Hello,

I just installed LL 4.0 on a Dell Optiflex 760 with 4 GB RAM and Intel Core Duo E8400...and a 120 GB SSD to boot on.

Previously this PC was with ll 3.8 and a 160 gb HDD.
With LL 3.8 and HDD, boot time was pretty good, around 1'30"
With LL 4.0 and SSD, boot time is 15 "

I have suppressed Virtualbox as described in installation posts and have modified /etc/fstab file to add entry :
tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0

and modified /sda1 entry in the same /etc/fstab file as follows :
UUID=a59ac022-1a29-494b-baf2-4e7ef52bb22a /               ext4    noatime,errors=remount-ro 0       1


     
LL 4.8 running on Dell Optiflex 760
LL 4.8 running on Asus X52J
LL 4.8 running on Toshiba Satellite C670-14W
LL 3.8 (32 bits) running on HP Pavilion
LL 5.0 running on Samsung RV515

If you are not going to use vbox, try following Jerry's instructions he gave at the bottom of the Linux Lite 4.0 Final Release Announcement message (Performance Tips:).  Worked well for me when I installed LL 4.0. 
https://www.linuxliteos.com/forums/release-announcements/linux-lite-4-0-final-released/

Definitely try what charvie suggested above.
It speeded up boot very significantly from around 40 seconds to 13 seconds on the i7 laptop in setup (1), listed in signature below.

That kernel is NOT the one causing trouble.  The -24 is causing slow boot-ups.  So your trouble is something else.  Sorry I couldn't help but it was worth a try.

I moved this to it's own thread as your SSD is new. Will you be running VirtualBox?

Check your kernel version. Can be done easily going Menu->System->System Info->Operating System.
If it is Linux 4.15.0-24 generic you maybe having the same problem as me. 

If it is as mentioned above after the boot splash screen with whirling thing, move your mouse around and see what happens.
